staging: android: sync: Fix memory corruption in sync_timeline_signal().

The android_fence_release() function checks for active sync points
by calling list_empty() on the list head embedded on the sync
point. However, it is only valid to use list_empty() on nodes that
have been initialized with INIT_LIST_HEAD() or list_del_init().

Because the list entry has likely been removed from the active list
by sync_timeline_signal(), there is a good chance that this
WARN_ON_ONCE() will be hit due to dangling pointers pointing at
freed memory (even though the sync drivers did nothing wrong)
and memory corruption will ensue as the list entry is removed for
a second time, corrupting the active list.

This problem can be reproduced quite easily with CONFIG_DEBUG_LIST=y
and fences with more than one sync point.

Merge tag 'iio-for-4.1a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new drivers, cleanups and functionality for IIO in the 4.1 cycle.

New drivers
* CM3323 color sensor.
* MS5611 pressure and temperature sensor.

New functionality
* mup6050 - create mux clients for devices described via ACPI. The reasoning
     and approach taken in this patch are complex.  Basically there is no
     otherway of finding out what is there than by some esoteric look ups in
     the ACPI data.
* cm3232 - PM support
* itg3200 - suspend/resume support
* mcp320x - add more ADCs to the kconfig to reflect what the driver supports
     (this patch and the bindings got left behind when the support was added
      a while back).

Docs / utils
* ti-adc128s052 - DT bindings.
* mcp3422 - DT bindings.
* mcp320x - DT bindings
* ABI docs for event threshold scale attributes, in_magn_offset, proximity
  scan_element and thresh falling/rising values for accelerometers.  All
  elements long in use that have slipped by being explicitly documented.
* Tidy up the tools previously in drivers/staging/iio/Documentation and move
  them out to /tools/iio. Yet another move that should have happened long ago.
  This time Roberta Dobrescu did the leg work.  Thanks!

Core Cleanups
* Export userspace IIO headers.  We should have done the appropriate header
  splitting a long time ago. Thanks to Daniel for sorting this out.

* Refactor the registring of attributes for buffers to move all non-custom
  ones to a vector allowing easier additions to the current set in the future.

Driver Cleanups
* gpiod related cleanups.  Make use of the additional parameter to specify
   initial direciton to avoid extra code.
* bmc150 - Various refactorings to reduce code repitition and prepare for
           hardware buffer support.  Some of these cleanups are good even
   without the new functionality.
* kmx61 - direct use of index to an array avoiding a structure element which
          was always the index to an element in an array of that structure.
* vf610 - avoid incorrect type for return from wait_for_completion_timeout.
* gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
* ade7754 - improve error handling including suppressing some build warnings.
* ade7759 - improve error handling including suppressing some build warnings.
* hmc5843 - Long line and indentation fixes. Also some constifying of various
      constant data.
* ade7854 - 80+ character line splitting.
* ad2s1210 - fix wrong printf format string.
* mxs-lradc - fix wrong printf format string.
* ade7954-i2c - code alignment fixes and other trivial but worthwhile bits.
* periodic rtc trigger - make the frequency type an unsigned int as it
  is always treated as such.
* jsa1212 - constify struct regmap_config as it is constant.
* ad7793 - typo in the MODULE_DESCRIPTION
* mma9551 - check gpiod_to_irq errors.  Note that this doesn't actually cause
    any trouble but is worth tidying up as obviously incorrect.
* mlx90614 - refactor the register symbols to make it clear which reads are to
    RAM not PROM.

"dgnc_NumBoards" is the number of filled out elements in the

They are the number of channels in the ->channels[] array so these tests
should be ">=" instead of ">" so we avoid reading past the end of the
